Benefits of technology

Enables simultaneous mounting of multiple connecting rods for precise alignment and efficient heating of busbars, improving adaptability and safety during assembly, reducing the risk of electrical hazards, and optimizing space usage without compromising electric clearance or increasing costs.

Problems solved by technology

However, increasing the length of overlapping may increase amounts of busbars resulted in increasing cost.
Electric clearance or phase distance between busbars may be reduced as a result of bolts used for fastening, in order not to reduce the electric clearance or phase distance, a distance between busbars needs to be increased, however increasing the distance necessarily enlarge an occupation space of busbars.

Abstract

A tool for connecting busbars has an hydraulic cylinder driving unit and an electric control unit. A stationary portion removably is connected to a second busbar, a movable portion is removably connected to a first busbar a loading portion is for clamping connecting rods. The movable portion is movably connected to a first and second stationary shaft of the stationary portion, the movable portion is fixedly connected to the hydraulic cylinder driving unit by a movable shaft, the movable shaft is driven to slide axially with respect to the first and second stationary shaft by the hydraulic cylinder driving unit, the loading portion rotates around the second stationary shaft. It is achieved that a plurality of connecting rods are simultaneously mounted to busbars and that two busbars are connected in a form of butt-and-butt connecting.

Description

RELATED APPLICATION[0001]This application claims priority to China Patent Application No. 201710230067.8 filed on Apr. 10, 2017, the entire content of which is hereby incorporated by reference.FIELD OF THE INVENTION[0002]The invention relates to an electric device, especially to a tool for connecting busbars.DESCRIPTION OF PRIOR ART[0003]In a field of power distribution, partly overlapping two busbars is usually used to be a manner of a connection between two busbas, then using bolts and nuts to fasten them. As this manner required, there is a certain length of two busbars needed to overlap for keeping a current density of a touching surface within a normal range of values so as to make the connecting part meet requirements of related standards. In order to keep a low temperature rising of an electric device, usually a length of overlapping is increased for increasing a touching surface so as to reduce a current density thereof. However, increasing the length of overlapping may incr...
